Subject: [PATCH v3 0/1] platform/chrome: Update cros_ec sysfs attribute after sensors are found
Date: Wed,  4 Aug 2021 14:31:38 -0700	[thread overview]
Message-ID: <20210804213139.4139492-1-gwendal@chromium.org> (raw)

Attribute "kb_wake_angle" in /sys/<cros_ec hw path>/chromeos/cros_ec,
used to set at which angle the embedded controller must wake up the
host, is only set when there is at least 2 accelerometers in the
chromebook.

The detection of these sensors is done in cros_ec_sensorhub, driver that
can be probed after the cros_ec_sysfs driver that sets the attribute on
behalf of the chromeos EC class driver.
Therefore, we need to upgrade the sysfs group in the sensorhub probe
routine.
